Gayle Fallon of the American Federation of Teachers disagreed with Keller’s solution and said teachers would not be able to shoot a young attacker.

“In a lot of cases, the perpetrator is a kid,” she told CBS DFW. “Look at Columbine, it was a 14-year-old kid. You tell me a teacher is going to look in the eyes of a 14-year-old and pull the trigger — it’s not in their emotional make up.”

She proposed additional security, something Keller said would just lead to a delay in reaction time to emergency situations.

“Our personal safety is our responsibility, unfortunately the police and the military cannot be everywhere,” Keller told the news station. “When seconds count, the police are just minutes away.”

Even in Connecticut, which has some of the harshest gun laws in the nation, gun regulation and a tight security system could not stop Adam Lanza from harming innocent people. And while Fallon asserted that a teacher would not be able to take the life of a young shooter, the alternative is watching that individual murder students. That is not in a teacher’s ’emotional make up.’

Perhaps it’s time to consider armed and properly trained teachers a viable possibility — it might be the only way to give them the ability to protect their students.
